Hey silverspear I am new the the forum have many subarus but unfortunatly no SVX as of right now. I am buiding a Twin Turbo ER27. That is a neat project with the intake the only problem I see is this. You are using the copper to disipate the heat inside of the intake and in other words cool the intake charge down. The thing is since copper is such a good thermoconductor it is going to take ALL the heat coming off of the engine and transfer it into your intake charge. In order for you to combat the high temp of the engine transfering into your intake it will take a lot more the a few small fans to remove that heat. I am sure you probably have a trick up your sleave but just keep this in mind. I cant wait to see what you are going to do with this. I just wanted to give you a heads up.
